I get the following error when I create a simple BSP with SDK 2015.3:
I have not observed this error in the RHEL 5.9 OS.
However, I see this error on a RHEL 6.3 system.
The error occurs if the machine does not have Cairo Graphics installed.
In such cases, open the SDK with the following extra argument:
xsdk -vmargs -Dorg.eclipse.swt.internal.gtk.cairoGraphics="false"
